[RESEND,v3,0/4] STUSB1600 support on STM32MP15xx-DKx

I resend a part of my series [1] as the driver patches are already
merged. Bindings are missing and also device tree and config updates.

This series adds missing bindings for Type-C power-opmode property and
STUSB160x Type-C port controllers [2].
STUSB160x driver requires to get power operation mode via device tree,
that's why this series also adds the optional DT property power-opmode
for usb-c-connector to select the power operation mode capability and
a function to convert the power operation mode string into power
operation mode value.
Tested on stm32mp157c-dk2 [3], which has a Type-C connector managed by
STUSB1600, and connected to USB OTG controller.
